Ever since I read about using H2O2 to power torpedoes in WW2, I been
fascinated with it. In fact, some people (Armadillo Aerospace) is
using it to propell their lunar lander.
Seems that if you take 80% H2O2 and pass it thru a silver gauze as a
catalyst, you get 600 degree steam and oxygen. Add some methane to it
and you get steam and CO2. H2O2 is non-flammable and easy to store
and not too expensive.
Next, we combine this high temp steam generator with an efficient way
to make electricity, say a micro-turbine. I saw a Youtube video of a
guy who made a tiny (a few cubic inches) turbine that produced 50
watts of power from compressed air. Combine such a micro-turbine with
the H2O2 steam generator and you have a great way to generate
electricity. Scale up a little to get a few KW with almost no noise
and NO flame at all
One could use the turbine directly to turn a gear system to turn a
prop too.
Compared to gasoline, H2O2 is not very dangerous because it is non-
flammable. It is however a powerful oxidizing agent but so what.
Major problem I see is that you cannot spill it onto any oily material
because that produces instant flames.
H2O2 has a great energy density compared to any battery system and one
could imagine buying tiny sealed vented bottles of it to plug into
your micro-turbine to run your computer for many hours.
